When I get my Lego Technic Porsche 911, do I build it, or leave it in its box and sell it for profit once it gets discontinued?

A set like this is going to more than double its value the second it’s discontinued, provided it’s still sealed in the box. I could build it, which would be awesome, but I’ll have nowhere to display it since it’s so big. And once I build it... that’s sort of it?
